To all whomc't may concern: I

Be it known that I, ELMER E. STOCKTON, a citizen of the United States,residing at Bristol, in the county of Hartford and State of Connecticut,have inventeda new and useful Improvement in Alarm-Clocks; and I dohereby declare the following, when taken in connection with theaccompanying drawings and the characters of reference marked thereon,'tobe a full, clear, and exact description of the same, and which saiddrawings constitute part of this application, and represent, in-

My invention relates to an improvement in that class of smallalarm-clocks known to the trade as nickel alarms from having beenoriginally supplied to the trade in cylindrical nickeled cases. Thebells of these clocks have been variously arranged. The early practicewas to mount the bell upon a bell-post rising from the center of the topof the case, and to strike it by ahammer the tail of whichwibrated in aslot formed in the top of the case; but clocks with their bells solocated were objectionable for the reason that in this exposed positionthe bell was apt to be displaced with reference to the bell-hammer bythe canting of the bell-post. Another objection to these clocks was,that the location of the bell in this position called for a largepastebo-ard packing box of special construction. Other clocks of thetype had their bells arranged centrally belowt their cases, betweentheir legs, or in a supplemental base. Nickel alarm-clocks with theirbells arranged above and below their cases were succeeded by clockshaving large bells arranged concentrically at the back of their cases,outside of the same and perforated for the passage of the winding andsetting arbors of the clock. Clocks having these large bells, requiredthe use of long windii'ig and setting arbors and special packing boxes,all entailing extra expense. Furthermore the bells being exposed had tobe finished to correspond to the exterior finish of the cases, involvingextra expense. Clocks having large concentric bells at the back on theoutside of their cases, were followed by clocks having concentric bellslocated within the r cases, either in front or at the rear of theirmovements. These large concentrically arranged bells, whether placedinside or outside of the case, are expensive, and necessitate the makingof cases of extra depth from front to rear.

The object of my present invention is to 1 overcome the objections aboverecited and produce a nickel alarm-clock adapted by its construction andarrangement of parts to have its bell located within its case without,however, enlarging the same for the purpose, and in such position tosecure the best results from the bell-hammer.

With these ends in view, my invention consists in an alarm-clock havingcertain details of construction and arrangements of parts as will behereinafter described and pointed out in the claims. 7

In carrying out my invention as herein shown, I locate the bell 2 in thespace 3 between the righthand edges of the front and rear movementplates 4 and 5, and the right hand portion of the circular sheet metalband 6 of the cylindrical clock-case. The bell 2 is located edgewise inthe space 3 so as to extend, as it were, from front to rear at a rightangle to the plane of the movement-plates and parallel with the band 6of the clock-case. The bell is located entirely outside of the movement,and, as shown, opens inward so that its edge is adjacent to themovement, and therefore in the most advantageous position forcooperation with the striking mechanism thereof, as will be explainedlater on. As thus arranged, the said bell 2 is located directly oppositethe main time-wheel 7 and main time-spring 8, these parts of thetime-train of the clock-move ment projecting into the space 9 betweenthe left hand edges of the said front and rear movement-plates l and 5,and the left hand portion of the band 6. If desired, however, thisarrangement might be reversed, and the bell 2 located at the left handof the movement, and the wheel 7 and spring 8 located at the right handof the movement. Under either arrangement it will be observed that thespaces 3 and 9 respectively located between the vertical edges of themovementplates 1- and and the sides of the band (5 of the case, aremeasurably utilized. The corresponding space 10 between the bottom edgesof the plates 4 and 5. and the bottom portion of the band (3, isreserved for the projecting portion of the ba1ance-wheel 11 and itsspring 12. the said wheel and spring being protected in this position bythe heavy wrought metal brackets 13 riveted at their upper ends to theprojecting front ends of the pillars 11 joining the lower ends of thefront and rear movement plates 4: and 5. These brackets stitfen the band6 and re ceive the threaded inner ends of the turned peg-like feet 15which support the case and which are so close together as to make thebase 6 relatively stilf between them, and therefore protective of thebalance-wheel 11 and spring 12, the most delicate parts of theclock-structure. The balance-wheel staff 16 is pointed at its ends toform pivots which run in screw-studs 17 mounted in the lower edges ofthe plates 5 and 6 as clearly shown in Fig. 4. v

The space 18 bet ween the upper edges of the plates 1 and 5 and theupper portion or top of the band 6 is occupied by the projectingportions of the alarm crown wheel 19, the alarm verge 20, the alarm mainwheel 21, the alarm main spring 22, and by the hammer tail 23 whichextends horizontally over the movement from left to right, or from rightto left according to the arrangementof the alarm bell 2 in the space orin the space 9 as the case may be. As shown, the hammer-tail extendsfrom left to right, its left hand end being secured to the verge-arbor24, and its right hand end being provided with a hammer 25 located closeto the top of the hell 2. In this connection, I must point out that byarranging the bell in the vertical plane on one side or other of themovement, the bell-hammer is aided by gravity in striking it, wherebyfar better re sults are secured than when the bell-hammer must beoperated in opposition to gravity.

The horizontal arrangement of the hammer-tail 23 as described. brings itinto con venient position for its being operated upon directly forstopping the alarm by means of a vertically arranged plunger 26 thelower end of which engages directly with the upper edge of thehammer-tail 23 at a point toward the left hand end thereof. The saidplunger 26 is mounted in a ring-head 27 rovided. as shown. with anangular rin 28. the upper end of the plunger being provided with apush-button in the form of a ball 29 located within and protected by thesaid ring 28. At its lower end the ringhead 27 has a concentric threadedstem 30 adapting it to be mounted in the horizontally arranged forwardlyprojecting upper arm of :1V wrought metal bracket ll corresponding tothe brackets 13 before mentioned. and having its lower end fastened tothe upper reach of the front movementplate 3 by a rivet 32. Thehorizontal upper arm of this bracket 31 tits snugly within the extremeupper portion of the band 5 and rigidly supports the same. The saidplunger 26 is controlled in position by a leaf spring 3 the forward edgeof which is notched to receive the lower end of the plunger and the rearend of which is secured by a rivet 34 to the lower face of the forwardlyprojecting arm of the bracket 31, as clearly shown in Fig. 3. It willthus be seen-that the upper space 18, which is the space between the'upper edges of the plates 4 and 5 and the upper portion of the band 5,is also utilized for the reception of tlre hammer-tail 23. the lowerportion of the plunger 26, the spring 22, and portions of the bracket31.

Under the described construction and arrangement of parts. I have soutilized the spaces between. the edges of the movement plates of theclock-movement and the band of the clock-case as to provide for thelocation of the hell 2 within the case without enlarging the case eitheras to diameter or as to depth-and at the same time to so locate, thehell 2 as to utilize the action of gravity in the operation of thebell-hammer 25, and also to locate the hammer-tail where it may beoperated upon directly for stopping the alarm by means of a plunger 26mounted in the ringhead '27.

As herein shown. the bell 2 is secured by a rivet 34 to the projectingouterend of a curved arm 35 formed upon the outer edge of a sheet-metalbracket ill) superimposed upon the rear movement-plate 5 and secured bynuts 37 to the threaded. projecting rear ends of the pillars l4 and 39employed for holding the movement-plates "t and 5 together. It will benoticed that. the hell 2 receives the projecting portion of the thirdwheel 40 of the time-train which may be of any approved constriu-tion.and therefore not necessary to show or describe in detail in order tosecure an understanding fof my present invention. It will also benoticedthat the bell 2 takes advantage of the depth of the case from front toreaiprojecting considerably beyond the faces of the front and rearmovement plates 4 and I claim 1.
